Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of embodiments of the invention, which are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.
In the present exemplary embodiment, a touch display substrate is first provided. Referring to fig. 1, the touch display substrate may include: a plurality of first electrodes 100 extending in a first direction X and a plurality of second electrodes 200 extending in a second direction Y intersecting the first direction X. At least one of the first electrodes 100 has a hollow area 101 therein, and a predetermined pattern 102 is insulated in the hollow area 101. The plurality of second electrodes 200 are spaced apart from the plurality of first electrodes 100 to form a capacitive coupling node 300 therebetween. Illustratively, the first direction X and the second direction Y may be 90 °, but are not limited thereto.
Through the touch display substrate, on one hand, stress applied to the OLED panel by the touch display substrate in the bending process can be reduced by the aid of the hollowed area 101, so that the touch display substrate is bent at a smaller radius, and on the other hand, the preset pattern 102 is arranged to reduce the light transmittance of the hollowed area 101 and enable capacitor signals on the touch display substrate to be uniform, so that display uniformity and touch accuracy of the touch display substrate are improved.
Next, each part of the above-described touch display substrate in the present exemplary embodiment will be described in more detail with reference to fig. 1 to 2.
In one embodiment, the shape of the predetermined pattern 102 may include one or more of a diamond shape, a rectangular shape, and a triangular shape, but is not limited thereto, and may be set according to the requirement. For example, the preset pattern 102 may be arranged in a diamond shape. The predetermined pattern 102 is made of a conductive material that is the same as or different from the material of the first electrode 100 and the second electrode 200. For example, the material of the predetermined pattern 102 may be an ITO (Indium Tin Oxide) transparent electrode or an IZO (Indium Zinc Oxide) transparent electrode, or an ITO and IZO composite transparent electrode, or other transparent electrodes in the prior art that can implement the present invention. But is not limited thereto.

In one embodiment, the projection of the predetermined pattern 102 on the touch display substrate and the projection of the first electrode 100 with the hollow area 101 on the touch display substrate do not overlap with each other, so that the non-overlapping arrangement ensures that the predetermined pattern 102 and the first electrode with the hollow area are separated from each other, and the reduction of the bending resistance of the touch display substrate due to the overlapping or connection of the predetermined pattern 102 and the first electrode with the hollow area can be avoided. But is not limited thereto and can be set by the user according to the requirement.
In an embodiment, the shape of the hollow area 101 is not limited, and the hollow area 101 is configured to enable the touch display substrate to extend a longer distance when being bent, so as to prevent the touch display substrate from being broken due to the fact that the touch display substrate cannot provide a deformation degree greater than the material property of the touch display substrate, improve the stretchability of the touch display substrate, reduce the risk of breaking during the bending process, and reduce the stress applied to the OLED panel by the touch display substrate during the bending process, thereby achieving the smaller-radius bending of the touch display substrate. For example, the shape of the hollowed area 101 may be a diamond shape, but is not limited thereto, and may be set according to the requirement. In view of simplifying the processing steps of the first electrode with the excavated area and the reserved pattern 102, improving the manufacturing efficiency, and avoiding the waste of raw materials, equipment, labor and power caused by manufacturing the electrodes for many times, in the embodiment of the present invention, the first electrode with the excavated area and the reserved pattern 102 are manufactured at the same time, and the first electrode with the excavated area and the reserved pattern 102 have the same thickness and the same material, but not limited thereto, so the operation is simpler.
In one embodiment, the first electrode 100 having the hollow area 101 may be located in the folding line area 400 of the touch display substrate, such that the bending resistance of the folding line area 400 of the touch display substrate may be improved, and the stress applied to the OLED panel by the touch display substrate during the bending process may be reduced, but is not limited thereto. In at least one embodiment of the present disclosure, at least a portion of the touch display substrate corresponding to the folding line area 400 is formed of a flexible material, so that the folding line area 400 can be partially bent, for example, bent by 180 degrees.
In an embodiment, the first electrode 100 and the second electrode 200 are identical in shape, for example, the first electrode 100 and the second electrode 200 may be both diamond-shaped, so that the consistency of the capacitance of each touch point can be ensured to some extent, but is not limited thereto.
In one embodiment, the first electrode 100 is a driving electrode and the second electrode 200 is a sensing electrode, or the first electrode 100 is a sensing electrode and the second electrode 200 is a driving electrode, but is not limited thereto, and can be set as required.
In one embodiment, the first electrode 100 and the second electrode 200 are made of the same material, and the materials are both transparent conductive materials, so that the light transmittance of the touch display substrate can be improved, and the display effect is better, but not limited thereto. For example, the first electrode 100 and the second electrode 200 may be made of ITO (Indium Tin Oxide) transparent electrodes or IZO (Indium Zinc Oxide) transparent electrodes, or ITO and IZO composite transparent electrodes, or other transparent electrodes in the prior art that can implement the present invention. But is not limited thereto.
